TALKING-MACHINE.

Specification of Letters Patent.

Application filed August 31. 1906. Serial No 332,729-

To all whom it may concern.- f

Be it known that I, EDWARD T. PALMER, a I nited States, residing inPhiladelphia, Pennsylvania, have invented certain Improvements inTalking-Machines, of which the following is a specification.

One object of my invention is to provide a sound recording andreproducing machine in which the stylus and its supporting member shallbe revolubly supported relativel to a stationary record, which may be oft e ordin ary disk type. i

It is further desired to provide a device commonly known as a talkingmachine, especially designed for use with records of the disk form,which shall have but few parts and these of a relatively simple andinexpensivenature. I also desire to produce a talking machine whichshall require but little attention and be of such a nature as to noteasily get out of order.

5 These objects I attain as hereinafter set forth, reference being hadto the accompanying drawing, in which v Figure 1, is a plan view of themachine made in accordance with my invention; Fig. 2, is a sideelevation, partly in section, of the device shown in Fig. 1 Fig. 3, isan end view; Fig. 4, is a sectional view on the line 44, Fig. 2; Fig. 5,is a perspective view of the stylus; and Figs. 6 and 7, are views of amodification.

In the above drawing, A is a base or stand of any suitable form havin atits center a bearing in which is remova ly supported a vertical spindleb. This spindle has at its upper end a crank b, there being also fixedzontal plane, a relatively heavy and preferably metallic plate B, whichmay advantageously be of the elongated shape shown in the figures,although I do not limit myself to such form. On one of the lobes of thisplate is carried a U-shapedor forked piece b inov able on a verticalpivot. A block C is pivoted to the arms of the U- shaped piece 12 asillustrated clearly in Figs.- 2 and 3, and on the end of this block issecured the horn D, the horn in the present instance having a reducedportion d which passes over the end of the block O. and is preventedfrom turning-thereon by a pin 0 on the block which extends into a slotcl in the horn.

Directly secured to aproje'ction d on the Fig. 2.

the base A, preferably on. a sheet of felt or 1 other soft material, asindicated in Fig. 2. The record disk is stationary and the horn with thestylus turn on the spindle bas a pivot.

Mounted between a block tering a cavity in the block, as illustrated inThis spring tends to keep the stylus down onto the record, overcomingthe centrifugal force due to the rotation of the metallic plate B whichcarries the horn and stylus.

It will be seen that there is a direct connection between the stylus andthe horn, thus I dispense with an intermediate carrier.

In some instances the block C may be permanently secured to they horn D,but I preferably make it detachable, as shown.

In Figs. 6 and 7 I have illustrated a modification in which there is asaw kerf out in the block G into which pro'ects a standard extendingfrom the pivot plate I). In Fig. 6, I have also shown a flat spring z"in place of the coiled spring illustrated in Fig. 2. The block C in thisinstance is slotted at 0 so that the end of the block will yield whenthe projection b and the C is a coiled spring 45, the spring enhorn isforced over it, thus there is sufiicient elasticity in the block to,hold the horn rigidly in position without other fastenings.

When it is desired to the spindle b .with the plate B and its parts isremoved from the base A, after which a reoord disk F is placed on saidbase concentric with the bearing 6 said spindle?) and its attached partsare then replaced and the stylus e permitted to rest upon the disk F. Onrevolving the plate B y turning the crank b the stylus, which is carriedby the horn, fol lows the spiral record groove in the disk, causingvibration of the horn which in turn causes sound waves to be produced.The

operate the machine sound waves are reproductions of the wavesoriginally recorded on the disk, being due to the co-operation of thestylus and its parts with the record in the manner understood by thoseskilled in the art.

In some instances any suitable device whicli'will cause the sound wavesto be reproduced can be used in place. of the. horn, although I preferto use a horn in most instances.
